Interesting, updated daily “Power Barometer” put together by the Denver Research Group on behalf of the Washington Post. The Power Barometer tracks each nation in terms of it’s own ability to influence world events in line with it’s own goals – so you’re seeing how each interest is meeting it’s own goals, not necessarily a direct “win/loose” relationship between the competitors. The Post provides a brief summary of the methodology.
